Procedure

A mixture of (5R)-3-[3-fluoro-4-[4-[(phenylmethoxy)acetyl]-1-piperazinyl]phenyl]-2-oxo-5-oxazolidinecarboxamide (Step 2, 260 mg, 0.570 mmol) and 10% palladium-on-carbon (61 mg, 0.0570 mmol) in a mixture of methanol (5 mL) and EtOH (23 mL) is shaken under a 40 psi hydrogen atmosphere on a Parr apparatus for 22 h. The catalyst is then removed by filtration through a pad of Celite, rinsing with tetrahydrofuran (200 mL), and the filtrate is concentrated under reduced pressure and triturated with methanol/diethyl ether. Filtration then provides the title compound, mp 232-235° C. (dec.); MS (ESI+) for C16H19FN4O5 m/z 367 (M+H)+; [α]25D=−20 (c 0.98, DMSO).
